[0101] When the door handle 101 is pulled out, the second hook 102
is detached from the second hook receiving portion 24c.
Accordingly, the second door 100 may completely open the second
washing space 22.
[0102] The second door frame 110 may include a door hole 118
provided such that the inside of the second tub 24 may be seen when
the second door 100 closes the second opening 26. The door hole 118
may be formed to penetrate the inside and the outside of the second
tub 24.
[0103] The second door frame 110 may include an insertion portion
116 into which at least a portion of a first sealing member 131,
which will be described later, is inserted. The insertion portion
116 may be formed along a circumference of the door hole 118.
[0104] The insertion portion 116 may include a fixing portion 116a
for fixing the first sealing member 131. The fixing portion 116a
may be continuously formed along the circumferential direction of
the door hole 118. A plurality of protrusions may be intermittently
disposed in the fixing portion 116a along the circumferential
direction of the door hole 118. A plurality of protrusions may be
intermittently disposed on the fixing portion 116a along the
circumferential direction of the door hole 118. The fixing portion
116a may be inserted into an insertion groove 131a of the first
sealing member 131. Accordingly, the first sealing member 131 may
be fixed to the second door frame 110.
[0105] The second door frame 110 may include a water collecting
space 111 for collecting water flowing along one surface of the
second door 100 when the second door 100 opens the second opening
26, and a water collecting cover portion 115 for covering at least
a part of the water collecting space 111.
[0106] Specifically, the second washing apparatus 20 forms a water
flow inside the second tub 24 in the process of washing the
laundry. By this water flow, a part of the washing water adheres to
the inner surface of the second door 100. The washing water adhered
to the inner side surface of the second door 100 flows in the
direction of gravity along the inner surface of the second door 100
when the second door 100 is opened after washing is completed.
[0107] In order to prevent the washing water flowing in the
direction of gravity from falling into the laundry that has been
washed in the second washing space 22 and wetting the washed
laundry again, the second door frame 110 may include the water
collecting space 111.
[0108] The water collecting space 111 may be disposed at one end of
the second door frame 110 adjacent to a pivot axis with respect to
the second tub 24. The water collecting space 111 may be provided
to be positioned at a lower end portion of the second door 100 when
the second door 100 opens the second opening 26 in order to collect
water flowing in the direction of gravity along the inner surface
of the second door 100. The water collecting space 111 may be
formed in the insertion portion 116 of the second door frame
110.
[0109] The water collecting space 111 may be in communication with
the outside through an inflow gap 112. Water existing on an inner
side surface of the second door cover 120 may move downward by
gravity when the second door 100 is opened, and then may flow into
the water collecting space 111 through the inflow gap 112.
[0110] The inflow gap 112 may be formed between the second door
cover 120 and the water collecting cover portion 115, which will be
described later. The inflow gap 112 may guide water to the water
collecting space 111. The inflow gap 112 may be formed as the water
collecting cover portion 115 is provided to be spaced apart from
one side surface of the second door cover 120. That is, the inflow
gap 112 may be formed as the second door cover 120 is assembled
with the second door frame 110 in a state in which a portion of the
second door frame 110 on which the water collecting cover portion
115 is provided is spaced apart from the second door cover 120 by a
predetermined distance.
[0111] The water collecting cover portion 115 may be disposed at at
least a portion of the door hole 118 along the circumference of the
door hole 118. The water collecting cover portion 115 may be spaced
apart from a portion of the second door cover 120 by a
predetermined distance to form the inflow gap 112 between water
collecting cover portion 115 and the second door cover 120. The
water collecting cover portion 115 may be disposed to be spaced
apart from the inner surface of the second door cover 120 by a
predetermined distance.
[0112] When the washing water collected in the water collecting
space 111 is exposed to the user, the user may feel uncomfortable
looking at the washing water. In order to prevent this, the water
collecting cover portion 115 may be formed to cover an upper
portion of the water collecting space 111 when the second door 100
opens the second opening 26. Accordingly, the washing water
collected in the water collecting space 111 is not exposed to the
user, so that it is possible to prevent the user from seeing the
exposed washing water.
[0113] The water collecting cover portion 115 may include a drain
hole 117 formed to discharge the water collected in the water
collecting space 111 from the water collecting space 111 when the
second door 100 closes the second opening 26. The drain hole 117
may guide the water collected in the water collecting space 111 to
the inside of the second tub 24. The water collecting space 111 may
be in communication with the outside through the drain hole
117.
[0114] One or more of the drain holes 117 may be provided along the
circumference of the door hole 118. The drain hole 117 may be
formed to penetrate the water collecting cover portion 115. The
drain hole 117 may be disposed to be positioned in the front of the
water collecting space 111 when the second door 100 closes the
second opening 26. According to this configuration, the washing
machine 1 according to the embodiment of the present disclosure may
discharge the water collected in the water collecting space 111 to
the second washing space 22 only by an operation closing the second
door 100.
[0115] The second door cover 120 may be mounted to the second door
frame 110. The second door cover 120 may be configured to include a
transparent material so that the inside of the second drum 23 may
be seen from the outside of the second tub 24 through the door hole
118 even when the second door 100 closes the second opening 26. The
second door cover 120 may be configured to include a material
having transparency. The second door cover 120 may be configured to
include glass.
[0116] The second door cover 120 may be fixed to the second door
frame 110 through an adhesive. In this case, the adhesive may be
composed of a material capable of sealing a gap between the second
door cover 120 and the second door frame 110.
[0117] Alternatively, the second door 100 of the washing machine 1
may further include the first sealing member 131 for sealing the
gap between the second door cover 120 and the second door frame
110. The first sealing member 131 may be disposed along an outer
circumference of the door hole 118. The first sealing member 131
may prevent the washing water in the second tub 24 from flowing out
to the outside during the washing process. In addition, the first
sealing member 131 may prevent the wet steam from flowing out when
the second washing apparatus 20 performs washing using
high-temperature washing water.
[0118] The first sealing member 131 may include the insertion
groove 131a. The insertion groove 131a may be formed on one side
surface of the first sealing member 131 directing to the second
door frame 110. The fixing portion 116a of the second door frame
110 may be inserted into the insertion groove 131a. A portion of
the first sealing member 131 may be disposed in the water
collecting space 111.
[0119] The other side surface different from one side surface of
the first sealing member 131 formed with the insertion groove 131a
may be fixed to the second door cover 120. The other side surface
of the first sealing member 131 may be fixed to the second door
cover 120 through an adhesive. The upper surface of the first
sealing member 131 may be in surface contact with the lower surface
of the second door cover 120.
[0120] According to this configuration, the first sealing member
131 may seal the gap between the second door frame 110 and the
second door cover 120. In addition, because the first sealing
member 131 is inserted into the insertion portion 116 of the second
door frame 110, the first sealing member 131 is not exposed to the
user when the second door 100 is opened, thereby making the
appearance of the second door 100 neat.
[0121] The second door 100 may further include a second sealing
member 132 for sealing a gap formed between the second tub 24 and
the second door 100. The second sealing member 132 may seal a gap
formed between the second tub cover 24b and the second door 100.
The second sealing member 132 may be inserted into a fixing groove
114a formed in the first frame 114 of the second door frame 110.
The second sealing member 132 may be disposed at a lower end
portion of the second door frame 110. The second sealing member 132
may prevent the washing water in the second tub 24 from leaking to
the outside during the washing process. In addition, the second
sealing member 132 may prevent wet steam from flowing out when the
second washing apparatus 20 performs washing with high-temperature
washing water.
[0122] FIG. 8 is a side cross-sectional view illustrating the
second tub 24, the second door 100, and a state of washing water W
remaining in the second door 100 illustrated in FIG. 4 after
washing is completed and before the second door 100 illustrated in
FIG. 4 is opened. FIG. 9 is a view illustrating the flow of the
washing water W remaining in the second door 100 when the second
door 100 illustrated in FIG. 8 is opened. FIG. 10 is a view
illustrating the flow of the washing water W present in the water
collecting space 111 when the second door 100 illustrated in FIG. 9
is closed.
[0123] Referring to FIG. 8, when the second washing apparatus 20
completes washing, the washing water is present on the inner side
surface of the second door cover 120 of the second door 100.
Because the washing machine 1 according to the embodiment of the
present disclosure has a plurality of washing apparatuses, in a
case where the height of the top loading type washing apparatus is
low, more washing water may be present on the inner side surface of
the second door cover 120.
[0124] As illustrated in FIG. 9, when the user opens the second
door 100 to take out the washed laundry from the second tub 24, the
washing water existing on the inner side surface of the second door
cover 120 of the second door 100 moves in the direction of gravity
along the inner surface of the second door cover 120. The washing
water moving downward may be collected in the water collecting
space 111 through the inflow gap 112. The collected washing water
is not exposed to the outside by the water collecting cover portion
115. In addition, the washing machine according to the embodiment
of the present disclosure may prevent the laundry from being wet,
which is generated by dropping the washing water existing on the
inner side surface of the second door 100 to the washed
laundry.
[0125] As illustrated in FIG. 10, when the user puts new laundry
and closes the second door 100, water existing in the water
collecting space 111 moves inside the second tub 24 through the
drain hole 117. Similarly, when the user simply closes the second
door 100 without putting new laundry, water existing in the water
collecting space 111 moves inside the second tub 24 through the
drain hole 117. That is, the washing machine 1 according to the
embodiment of the present disclosure may discharge the water in the
water collecting space 111 to the second washing space 22 even if
the user does not separately remove the water in the water
collecting space 111.
